B.K.S. IyengarYoga, an ancient but perfect science, deals with the evolution of humanity. This evolution includes all aspects of one's being, from bodily health to self-realization.
B.K.S. IyengarHappy is the man who knows how to distinguish the real from the unreal, the eternal from the transient and the good from the pleasant by his discrimination and wisdom.
B.K.S. IyengarThe sleeping tortoise takes all its limbs into its carapace. So does the yogi: going back into himself he does not see anything worldly any longer, he makes peace in himself.
B.K.S. IyengarAs a mighty river which when properly harnessed by dams and canals, creates a vast reservoir of water, prevents famine and provides abundant power for industry; so also the mind, when controlled, provides a reservoir of peace and generates abundant energy for the human uplift.
B.K.S. IyengarAs a breeze ruffles the surface of a lake and distorts the images reflected therein, so also the chitta vrtti (fluctuations of mind) disturb the peace of the mind. The still waters of a lake reflect the beauty around it. When the mind is still, the beauty of the Self is seen reflected in it.
